Shoes and Socks!

I walked 6 miles last night on the treadmill in my new shoes that Brian got for me and the new socks that I ordered.....I have some pretty nasty blisters on the tops of my toes but am not sure if it's related to the socks or shoes or just the fact that I haven't walked that distance is a while! I think I am going to try to do another 6 (7 if feeling particularly ambitious!) tonight in both and see how it goes! I wonder, how does one go about addressing a "hot spot" on the top of a toe!!!! Anyone else having these issues?
Have a great day!
